Measuring jet energy loss and its fluctuations in the quark-gluon plasma

As high-momentum partons traverse the quark-gluon plasma created in heavy-ion collisions, they lose energy via collisional and radiative energy loss. The various microscopic mechanisms of energy loss have different dependencies on the path length traversed by the hard probe. Recently, multiple measurements have attempted to distinguish the differences in yields of high-momentum objects such as jets for different average path lengths, which will inform our theoretical understanding of the microscopic structure of the QGP and its interaction with colored probes. In addition, current and future measurements that can characterize fluctuations in jet energy loss that are currently not constrained experimentally, will be discussed.
